Abstract (en)
[origin: WO0038992A1] A packaging process is disclosed which includes the steps of providing a tray, providing an upper film which includes a sealant layer which is sealable to the tray, orienting the film to an orientation ratio of from about 6.0:1 to about 16.0:1, positioning a high profile product on the tray, extending the upper film above the tray and product, drawing the upper film into a concavity by differential pressure, maintaining the concave shape of the upper film while heating the film, removing gases from the space between the upper film and the tray and product, introducing a desirable gas into the space, releasing the upper film such that it shrinkis toward the product and the tray while the desirable gas is retained within the space and prevents close contact of the film with the lowermost portions of the product, and sealing the upper film to the flange of the tray, wherein at least the step of heating the film shrinks the film, thereby tensioning it onto and across the underlying product. The resultant package of the high profile product provides an in-store overwrap appearance.
